a semi-circle only has one line of symmetry
Triangle has 3 syllables: tri an gle
Every triangle has three angles, regardless of what kind of triangle it is.
44
The information was certainly known to Euclid.
a scalene triangle has no lines of symmetry
0 lines of symmetry
None.
7 there are 7
None
That will depend on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry but a scalene triangle has no lines of symmetry.
ZERO!
Depending on the triangle:A scalene triangle has no lines of symmetry.An isosceles triangle has 1 (one) line of symmetry.An equilateral triangle has 3 (three) lines of symmetry.
A scalene triangle has one order of rotational symmetry.
Well, an equilateral triangle has only one line of symmetry. So does and iscosolese. A scalene doesn't have an exact answer because it can have sides that have no way of being symmetric. * * * * * Incorrect! An equilateral triangle has three lines of symmetry - not just one. An isosceles (not iscosolese) triangle has one and a scalene has none.
The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
none. Wow I can't believe you asked that. >:D
